Help - how to reboot if data dont' send at database

[kae90]

Hi, I send the timestamp every 70 seconds to Firebase. I wanted to make sure that if the sending fails, for example due to a lack of internet connection (not Wi-Fi signal), the device reboots. I tried using aResult.isError(), but I can't get it to reboot.
I tried using aResult.isDebug(), but of course it reboots at boot time.
Thanks.

void TimeStamp() {
  object_t  json ;
  JsonWriter writer;
  timeClient.update();
  writer.create(json,"/T", timeClient.getEpochTime());
  Serial.print(F("Invio Timestamp - heap libera : ")); Serial.println(ESP.getFreeHeap());
  Database.update(aClient, "/info/" UID_UTENTE, json,processData , "INVIO_TS" ) ;
}


void processData(AsyncResult &aResult)
{
    // Exits when no result is available when calling from the loop.
    if (!aResult.isResult())
        return;

    if (aResult.isEvent())
    {
        Firebase.printf("Event task: %s, msg: %s, code: %d\n", aResult.uid().c_str(), aResult.eventLog().message().c_str(), aResult.eventLog().code());
    }

    if (aResult.isDebug())
    {
        Firebase.printf("Debug task: %s, msg: %s\n", aResult.uid().c_str(), aResult.debug().c_str());
    }

    if (aResult.isError()){
    Firebase.printf("Error task: %s, msg: %s, code: %d\n", aResult.uid().c_str(), aResult.error().message().c_str(), aResult.error().code());
    Serial.println(F("Riavvio dispositivo tra 5 secondi..."));
    delay (5000);
    ESP.restart();
    }

    if (aResult.available())
    {
        Firebase.printf("task: %s, payload: %s\n", aResult.uid().c_str(), aResult.c_str());
    }
}

void loop() {
  app.loop();
  processData(databaseResult);
}

This is not a library scope feature. Library works with SSL client, it does not know internet status.

I understand. Since I have devices installed in remote locations where the Wi-Fi signal isn't always very stable, I sometimes experience network outages. I noticed that when the network comes back, the device can no longer automatically connect to Firebase; I have to unplug it and plug it back in.

I used to use this (without processData):
if (!Database.update(aClient, "/info/" USER_UID, json)) { ESP.restart(); }

Unfortunately, during the network outage simulation, the reboot didn't occur.

I was wondering, isn't there an error code when sending to the database fails?
For example: code 00 sending failed.

I could use this via processData to reboot the device.

Thanks.

The error and status information from async result is from server returning status and payload. The only way you cannot get any status is your code is stuck at somewhere in your code and you have to debug it and make sure the loop is free of blocking code. You have to debug your SSL client too for WiFi and OOM.
